CPC7591 - Clare

CPC7591 Line Card Access Switch

The CPC7591 is a member of Clare’s next generation Line Card Access Switch (LCAS) family. This monolithic 4-pole solid state switch is available in either a 16-pin SOIC or a 16-pin DFN package. It provides the necessary functions to replace the 2-Form-C electromechanical ringing relay and it’s associated snubber circuitry on traditional analog line cards or .

Features

• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power up / hot plug state control
• Improved switch dv/dt immunity of 500 V/μs
• Small 16-pin SOIC or 16-pin DFN package
• DFN package printed-circuit board footprint is 60 percent smaller than the SOIC version, 40 percent smaller than fourth generation EMR solutions.
• Monolithic IC reliability
• Low, matched RON
• Eliminates the need for zero-cross switching
• Flexible switch timing for transition from ringing mode to idle/talk mode.
• Clean, bounce-free switching
• Tertiary protection consisting of integrated current limit.
